A study on the properties of ramie fabrics modified by plasma

摘要

The experiment about ramie fabrics processed by oxygen plasma was introduced. The mass spectrum of residual gas was measured by QMS, and quantities of hydrogen, carbon, oxygen and its compounds was observed from vacuum residual gas. The microcosmic characteristic of ramie treated by oxygen plasma show that the surface of the ramie fibre was effectively eroded by energetic particle and active molecules. It can be obviously seen from X-Ray diffraction analysis that the crystalline-indices of ramie fibre were slightly reduced after processing in oxygen plasma. Experiment results reveal that, with the increase of the processing time and power, the physical chemical properties such as wettability and dyeability were obviously improved.
